A system, a method, and an article of manufacture for adjusting CO emission levels in predetermined locations in a boiler system are provided. The boiler system has a plurality of burners and a plurality of CO sensors disposed therein. The system determines locations within the boiler system that have relatively high CO levels utilizing the plurality of CO sensors and then adjusts A/F ratios of burners affecting those locations to decrease the CO levels at the locations.

A technique is disclosed for evaluating and monitoring performance of a heat exchanger system. Operating parameters of the system are monitored and fouling factors for heat transfer surfaces of the exchanger are determined. Trending of fouling may be performed over time based upon the fouling factors, and a model of fouling may be selected from known sets of models, or a model may be developed or refined. Fluid treatment, such as water treatment regimes may be taken into account in evaluation of fouling. An automated knowledge based analysis algorithm may diagnose possible caused of fouling based upon sensed and observed parameters and conditions. Corrective actions may be suggested and the system controlled to reduce, avoid or correct for detected fouling.
